Looks like one of the hottest teams in the ballroom may not hoofing it tonight on Dancing With the Stars.

Derek Hough tweeted a photo of himself on Sunday getting a medical procedure done to his back, writing, "This is happening .... Ouch!"

And in his TV Guide blog post on Friday, he admitted, "I've been feeling under the weather and my back's been acting up the past week. I think it's just wear and tear. It's just that part of the season when it all starts to catch up to you and the show is getting tougher with multiple dances."

Us Weekly reports that Hough hurt his back dancing with Shawn Johnson last year, and re-injured it recently with his partner, Glee star Amber Riley. If he can't get cleared to dance tonight, Riley will perform with pro Henry Byalikov.

Meanwhile, you know how the show loves to keep us all in suspense.

The official DWTS Twitter feed wrote: "Update: Due to an injury, there is a chance @derekhough will not be dancing tonight. Stay tuned."
